Curious - does anyone else have a long gestation period?

post #1 of 6
Thread Starter 

I'm quite curious about this.  My first (by ultrasound) was 40 weeks and 2 days - but when he came out, the midwife said he was in there a lot longer.  My second (by ultrasound) was 43 weeks.  Yikes.  I'm wondering if I am destined to hold my babes forever - and I should mentally prepare for the stress of post-dating (a lot of stress and anxiety). 

 

I'm also wondering if weight has something to do with post-dating.  I don't know.  Does a higher BMI cause your body to hold baby longer?  Or is it that I'm just totally unlucky?

 

Thoughts?

 

I have tried looking this up on the web.  I tried by weight and by culture and couldn't find much convincing.

I noticed your post and it interested me because I have a few friends with high BMI who have had prolonged gestation. 

 

Here's one study reported: http://www.figo.org/news/maternal-obesity-linked-prolonged-gestation-003256

And another: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2344995/

Thanks for this.  This is something I have wondered about for a long time.  It's not my intention to give people the evidence to do routine inductions on heavy women (which I am against) but trying to understand what's happening with my body.  Honestly, I think much of my problem is an error in ultrasound dating.  I just don't trust it.  However, I did want to see if there was a correlation.  Even though these studies do not approach the subject, perhaps routine induction is not the way to go.  Maybe the babies of high BMI women are just not fully cooked - for one reason or another.  Maybe that's why the body hangs on a bit longer.  I don't know why that would be though.

 

When I was looking for a birth attendant this time around (my hb midwife was driven out of the biz) I checked some hospital midwife websites which said (in black and white) if you are this or this weight pre-pregnancy - that we will not be able to help you out.  They are stigmatizing women without anything even happening.  Most women start prenatals at what?  12 weeks?  It's absurd. In the beginning, most women are healthy.  Nobody is educated about how to eat in pregnancy - etc, etc, etc - so when they become 27-30 weeks - problems start.  This is not a problem just with big women, but with everyone.  My midwife says - and I tend to agree - that much of the sickness and pre-term births that women experience has to do with poor nutrition - rather than weight.

I ran across the same study and found it interesting. From a personal perspective, of the three children I've had one was an early induction after some BP issues. The other two were within 2 days of their due date (after) and I'm being induced at 39 weeks this go round so I can't say for sure but I am only 2 cm and seem to be nowhere ready at this point so I suspect it would have been the same this time around.

I had the opposite experience - I knew my exact ovulation date so never had an ultrasound for dating purposes. My babe measured about 2 weeks ahead for my entire pregnancy, and was born at 38w 1d and 9 lbs.

Wow, interesting! I will have to read those links. I went to 42 weeks with my first (said my placenta looked like 39 weeks) and almost 43 weeks with my 2nd (she was just 8 lbs 2 oz, my placenta was definitely DONE, though!)

 

I never thought of it as being connected to my weight...
